What is the volume percentage of a solution formed by dissolving 75.0 mL of a solute into 155.0 mL of a solvent?
Answers
Answer:
32.6
Explanation:
Volume percentage is the ratio of liquid solute in liquid solvent multiplied by 100. The equation for this is

. This calculation is is one of several ways to express the concentration of a solution.
Given:
Volume of solute = 75.0 mL
Volume of solvent = 155.0 mL
To Find:
Volume percent of the solution = ?
Step-wise Solution:
The volume percentage of a solution is the proportion of the volume of solute (mL) in a particular solution (mL).
To calculate the volume percent of the solution, use the following formula:
Percent by Volume (%v/v) = (Volume of solute (mL) ÷ Volume of solution (mL)) × 100
Volume of solution (mL) = Volume of solute (mL) + Volume of solvent (mL)
Now, to determine volume percent of solution in which 75.0 mL of solute is dissolved in 155.0 mL solvent steps are as follows:
Volume of solution (mL) = 75.0 mL (solute) + 155.0 mL (solvent)
= 230.0 mL of solution
Percent by volume (% v/v) = (75.0 mL of solute ÷ 230.0 mL of solution) × 100
= (0.3260) × 100
= 32.6 % v/v
Hence, the volume percent of the solution is 32.6 % v/v.
